Load Cell Mounting Modules – Precision Hardware for Weighing System Installation
Our load cell mounting modules and kits are precision-engineered hardware assemblies designed to correctly install and support load cells in platform scales, tank weighing systems, silo installations, and process weighing applications. Correct mounting is critical to weighing accuracy — a load cell that is poorly mounted, subject to side loads, or unable to accommodate thermal expansion will produce inaccurate, unstable readings regardless of its intrinsic accuracy. Our mounting modules are designed to eliminate these issues, providing stable load transfer, self-alignment, and protection against the off-axis forces that degrade load cell performance over time.
Load cell mounting modules are not simply mechanical supports — they are precision components that define how force is transferred from the structure to the load cell. Rocker pin and compression cup assemblies ensure the load is applied axially, preventing bending moments that would introduce measurement error. Self-aligning designs accommodate minor misalignment during installation and allow for thermal expansion of the structure without transmitting lateral forces to the load cell. Our range covers compression and tension load cell mounting for capacities from 50 kg to 50,000 kg, with standard industrial and ATEX-certified configurations available for hazardous area installations.

Frequently Asked Questions
Why do I need a mounting module — can I just bolt the load cell directly to the structure?
Bolting a load cell directly to a structure without a proper mounting module risks applying bending moments, side loads, and torsional forces to the load cell — all of which cause measurement errors and can permanently damage the load cell. Mounting modules ensure the load is applied axially (straight through the load cell’s sensing axis), protect against off-axis forces, and allow for thermal expansion of the structure. They are essential for accurate, long-lasting load cell installations.
What is a rocker pin mounting assembly?
A rocker pin assembly is a common compression load cell mounting configuration consisting of a hardened steel pin that sits in a cup on top of the load cell and a matching cup on the underside of the platform or structure. The curved surfaces allow the pin to rock slightly, accommodating minor misalignment and ensuring the load is always applied axially to the load cell regardless of small structural movements or thermal expansion.
How do I select the right mounting module for my load cell?
The correct mounting module depends on your load cell model, capacity, thread or flange configuration, and application type (compression, tension, or self-aligning). Many load cell manufacturers offer dedicated mounting kits for their specific models. Contact our team with your load cell make, model, and application details and we’ll identify the correct mounting hardware.
Are ATEX-certified mounting modules available?
Yes. We stock ATEX-certified mounting modules for use in Zone 1, Zone 2, Zone 21, and Zone 22 classified hazardous areas. In a hazardous area weighing system, all components within the classified zone — including mechanical mounting hardware — must be suitable for the environment. Contact our team to confirm the correct specification for your zone classification.
Can mounting modules be used outdoors?
Yes. Our stainless steel and alloy steel mounting modules are suitable for outdoor installations. For exposed coastal or highly corrosive environments, stainless steel construction is recommended. Ensure all mounting hardware is correctly torqued and protected against corrosion for long-term outdoor reliability.
